Pokemon was my childhood favorite, as it was for many other people. The variety to choose from within all the different Pokemon was staggering, and most were fairly cool looking. They all had their own types, movesets, stats, and abilities that made them unique from one another. For the most part, all of the Pokemon were, and still are, ascetically pleasing. The keyword in that sentence? MOST. NOT ALL. I'm here to count down the top 10 most unnecessary, and, quite frankly, idiotic Pokemon that Nintendo ever created. Keep in mind that I don't put anything that evolves into something else; Magikarp may suck, but Gyarados is kickass.
#10

Farfetch'd
I honestly don't understand why they had this. Most Pokemon that are terrible evolve into something that's slightly more reasonable: the Pokemon you trade in for Farfetch'd is Spearow, which sucks. However, if you raise it to a lousy level 20, it'll evolve into Fearow. Fearow is better than a Farfetch'd. Along with not having an evolution, Farfetch'd sports very horrible base stats for a one of a kind Pokemon. Even Mr. Mime, who I did consider putting on this list (he's a fucking MIME), has OK stats. Farfetch'd, admittedly, learns quite good STAB attacks such as Brave Bird and Air Slash, which is why he isn't #9 or below. Kudos to you, you pathetic, leek-twirling creature, you've made #10.

Lickilicky
Lickitung was a fairly bad Pokemon, but I decided to put its evolution, Lickilicky, up here instead. Why? Because Nintendo had 3 generations, or roughly 8 years, to make a substantially better evolution for Lickitung. Was Lickilicky a better evolution? NO. The fatter, much creepier looking evolution of Lickitung was still stuck with fairly average stats, insultingly average attacks, and average abilities, Oblivious and Own Tempo. The point of having a Pokemon, to me, was to get really excited when it learned a new, awesome attack. Would you begin to hyperventilate if your Lickilicky learned Slam, one of its best moves? Hopefully not.
Pokemon like Lickilicky: Probopass (Barely decent evolution of even worse Pokemon)
